Malte: The band was playing "Von Ewigkeit zu Ewigkeit" by Selig. You were dancing next to me when suddenly it hit me: "Ask her now!" I turned you around during the chorus and sang along.

Leonie: That's when you had that funny grin on your face and shouted: "Do you want to marry me?" I saw the look in your eyes and knew what was up: You were serious!

Malte: While Leo nodded with big eyes staring back at me, I thought: "Shoot, I didn't prepare anything." But I had an idea: I went to the bar to get the wire of a Champagne bottle and started twisting it until it turned into something resembling a ring.

Leonie: And that wire ring is what you put on my finger. I wore it proudly all night!

Laura: Everyone burst into applause after the last bang. That's when you came up to me, grabbed my hand, put a ring on my finger and kissed my hand without saying a word. I was floored and had no idea what was happening. "Well, now we are engaged!" you boldly pronounced, and everyone applauded.

Camillo: Well, of course I knew that that wasn't the end of it. So I whispered: "We are, right?" Thankfully you said yes!

Stefan: That's true, we both agreed at the time. But, to be honest, over the years I still thought it would be nice. I liked the idea of calling you my wife, if you know what I mean (laughs). Not in a possessive kind of way, but as a sign that we belong together. But I never really mustered the courage to tell you this.

Frieda: So it's a good thing that I proposed to you (laughs). It was spontaneous intuition. We were at the Penguin exhibition, Jule was busy bouncing around, you were holding my arm and I thought: "What if we got married after all?" As it turns out I was thinking out aloud, as you responded "Yes, I would love too!" …

Guests putting money and gold coins into the pockets of the couple? That's what a traditional engagement looks like in Turkey. It is said to bring good fortune and wealth to the couple.

In the Netherlands, custom has it that the man brings his chosen one a basket filled with goods. If she accepts, they are engaged. But if she says no to the gift, she literally returns the basket, which is a German phrase for rebuking someone ("einen Korb geben").

Bachelorette parties in Brazil can get quite risqué in Brazil: the girlfriends bring gifts, the contents of which must be guessed by the bride to be. She gets three chances to do so. If she's right, she gets to keep the gift. But if she's wrong she has to remove a piece of clothing and drink a shot of liquor. This makes for interesting Facebook or Instagram photo galleries.
